So I am looking at a 5 series (G30 model) with 20" BMW M Performance wheels, same as the attached. However the wheels have some kerb rash, in fairness the sales guy has told me he believes due to the wheel design where the spoke now affects the rim edge by protruding out of it, that a repair is no longer possible or not very easy. However newer BMW wheels seem to have this approach with either spokes protruding or a cut into the outer rim as part of the design, surely this cannot mean a repair is now no longer possible?

Is this the case or can it be repaired?
